HUAWEI EMUB Monitoring Unit HUAWEI WD2G1EMUB -48VDC 32 positions

· An EMUB provides a power input port and can be supplied with -48 V DCpower. The voltage can range from -36 V DC to -72 V DC.

· An EMUB can detect input voltage.

· An EMUB provides one port to connect a current-type humidity and temperature sensor working in the voltage of +12 V DC or +24 V DC and the current range of 4 mA to 20 mA. The temperature monitoring scope of the sensor is from -20°C to +80°C (-4°F to 176°F).

· An EMUB provides one port for monitoring four different analog signal inputs. If a voltage-type sensor is connected to the EMUB, the voltage ranges from 0 V to 5 V. If a current-type sensor is connected to the EMUB, the current ranges from 4 mA to 20 mA.

· The input signal type on the EMUB side is set by the DIP switch according to the input signal type set on the eNodeB side.

· An EMUB provides a +24 V DC port to connect a smoke sensor, a +24 V DC or +12 V DC port to connect a water sensor, a +24 V DC or +12 V DC port to connect an infrared sensor, and a dry contact-type port to connect a door status sensor. These ports meet the monitoring requirements of the system.
